RE: Cable-modem, dynamic IP, NAT and IPFWHi
I had the bright idea of putting a 10 base-t and a 100baset card in my box - the 10 for the internet and the 100 for the local LAN - never quite got around to switching the FreeBSD box of to put two 100 cards in!! FreeBSD just keeps on going - only reboot occasionally after a cvsup and a build world!!
To reset the modem - just un plug it - you need to do leave it off for approx 30sec to fully reboot it.
If you hard code an ip address into the external lan card of 192.168.100.2 - can you use a web browser to see 192.168.100.1? If I have got the address correct - fairly sure - you should get a web page up - this will prove that the card is taking to the cable mode.
Do you get any output in /var/log/message log file? - You haven't got any daft firewall rules in there to deny all traffic - which in the default in FreeBSD's eyes
Trust this helps?

Thanks. When you say 'reset' the modem, what did that entail for you? You suggest that a power-cycle won't do the job on its own.
I'll post my rc.conf file when I return home.

I don't think that would make a difference - I have a 10Mb card working with modem no problem. When I switched over from Win to Unix, though, I had t reset the modem (as opposed to off/on).
Could be wrong, of course...
